It has come to my attention that with the coming of vaccume packaging meat can be repackaged several times. For instance meat can come to a retailer in a box of vaccume packaged wholesale cuts. He then has a choice of breaking down those wholesale cuts to retail cuts and packaging those cuts for his meat counter or simply selling wholesale cuts as is at retail prices. The problem is that if the meat is not sold it can be repackaged with a vaccume package and try again thus doubling the shelf life. If this meat is still not sold it can be frozen sent elsewhere and try again. Some of it will deteriate a little under these circumstances thus really undermining the original guality of the meat. I have purchased meat in vaccume packing that was over six weeks old and it wasn't too bad, but I had to ask a lot of questions to find out how old it was. I think probably it would be more beneficial to consumers if the kill date was required on the package. The meat men just smile and say aged meat is the best and this is true to a point. But I have also purchased vaccume packaged meat at Sam's that was just plain rotten.
